Usage Guidelines

Usage Scenario

In AC backup scenarios, a backup AC IP address is configured so that APs can establish CAPWAP tunnels to the backup AC if they fail to establish CAPWAP tunnels to the primary AC.

Precautions

  • The configurations of primary-access and backup-access take effect only if both the commands are run to configure different IP addresses.
  • primary-access and backup-access cannot be configured with priority or protect-ac.
  • It is not recommended that primary-access and backup-access be configured with ac protect protect-ac or ac protect priority.
  • The configuration takes effect only after the AP is restarted.
  • The IP addresses specified by primary-access and backup-access must be configured the same as CAPWAP source IP addresses. If the CAPWAP source addresses have been translated using NAT, set the primary-access and backup-access IP addresses to the translated addresses.

Example

# Set the backup AC IP address to 10.33.12.78.

<HUAWEI> system-view
[HUAWEI] wlan 
[HUAWEI-wlan-view] ap-system-profile name sys1
[HUAWEI-wlan-ap-system-prof-sys1] backup-access ip-address 10.33.12.78
